如何使用xsl将cdata添加到xml文件

[英]how to add cdata to an xml file using xsl

问题描述

I am trying to wrap CDATA for the elements in an xml file. 我试图将CDATA包装为xml文件中的元素。

Another point i missed was, there are some elements with same names those need to be escaped from adding CDATA. 我错过的另一点是，有些元素具有相同的名称，需要从添加CDATA中转义。

This is the source xml file: 这是源xml文件： 

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<books>
    <jndi:binding name="books/cat/action/configs">
        <jndi:value type="java.lang.String">
            <urlConfig>
              <defaults catID="1983" subcatID="1987" method="get" onError="keep"/>
              <urlKey name="logo" altURL="def.com">
                <address>abc.com</address>
              </urlKey>
              <urlKey name="logo1" altURL="def.com">
                <address>abc.com</address>
              </urlKey>
            </urlConfig>
        </jndi:value>
    </jndi:binding>
    <jndi:binding name="books/cat/romance/configs">
        <jndi:value type="java.lang.String">
            <urlConfig>
              <defaults catID="1983" subcatID="1987" method="get" onError="keep"/>          
              <urlKey name="logo" altURL="def.com">
                <address>abc.com</address>
              </urlKey>          
              <urlKey name="logo1" altURL="def.com">
                <address>abc.com</address>
              </urlKey>  
            </urlConfig>
        </jndi:value>
    </jndi:binding>
<jndi:binding name="books/cat/thriller/configs">
    <jndi:value type="java.lang.String">
        abc.com
    </jndi:value>
</jndi:binding> 
<jndi:binding name="books/cat/classic/configs">
    <jndi:value type="java.lang.String">
        abc.com
    </jndi:value>
</jndi:binding>
</books>

I have tried to use the same trick that @Dimitre Novatchev has mentioned here at How to insert CDATA into XML text markup exported from Access 2003? 我尝试使用@Dimitre Novatchev在如何将CDATA插入从Access 2003导出的XML文本标记中提到的相同技巧。 . 。 But some how that's not working for me. 但这对我不起作用。

This is the xsl file that i tried: 这是我尝试过的xsl文件： 

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet 
version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
xmlns:jndi="urn:jboss:jndi-binding-service:1.0"  >
 <xsl:strip-space elements="*"/>
 <xsl:template match="node()|@*">
     <xsl:copy>
       <xsl:apply-templates select="node()|@*"/>
     </xsl:copy>
 </xsl:template>
</xsl:stylesheet>

Can some one suggest me how to add CDATA to an element and also need to add an additional line <?xml version="1.0" encoding="ISO-8859-1"?> at the beginning of CDATA. 有人可以建议我如何将CDATA添加到元素，还需要在CDATA的开头添加另一行<?xml version="1.0" encoding="ISO-8859-1"?> 。

Here is the expected out: 这是预期的结果： 

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<books>
    <jndi:binding name="books/cat/action/configs">
        <jndi:value type="java.lang.String">
        <![CDATA[

              <urlKey name="logo" altURL="def.com">
                <address>abc.com</address>
              </urlKey>
              <urlKey name="logo1" altURL="def.com">
                <address>abc.com</address>
              </urlKey>
            </urlConfig>
        ]]>

    </jndi:binding>

              <urlKey name="logo" altURL="def.com">
                <address>abc.com</address>
              </urlKey>          
              <urlKey name="logo1" altURL="def.com">
                <address>abc.com</address>
              </urlKey>  
            </urlConfig>

The problem is that you need to convert the XML that goes inside the CDATA sections into text. 问题是您需要将CDATA部分中的XML转换为文本。 This XSLT should do the job: 该XSLT应该可以完成以下任务： 

<xsl:stylesheet 
  version="1.0" 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:jndi="urn:jboss:jndi-binding-service:1.0">

  <xsl:output method="xml" indent="yes" cdata-section-elements="jndi:value"/>

  <xsl:template match="jndi:value">
    <xsl:copy>
      <!-- Copy the attributes -->
      <xsl:apply-templates select="@*"/>
      <!-- Convert the contained nodes (elements and text) into text -->
      <xsl:variable name="subElementsText">
        <xsl:apply-templates select="node()" mode="asText"/>
      </xsl:variable>
      <!-- Output the XML directive and the converted nodes -->
      <xsl:value-of select="concat('&lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;',$subElementsText)"/>
    </xsl:copy>
  </xsl:template>

  <!-- Copy text nodes as text -->
  <xsl:template match="text()" mode="asText">
    <xsl:copy/>
  </xsl:template>

  <!-- Copy elements as text -->
  <xsl:template match="*" mode="asText">
    <xsl:value-of select="concat('&lt;',name())"/>
    <xsl:for-each select="@*">
      <xsl:value-of select="concat(' ',name(),'=&quot;',.,'&quot;')"/>
    </xsl:for-each>
    <xsl:value-of select="'&gt;'"/>
    <xsl:apply-templates select="node()" mode="asText"/>
    <xsl:value-of select="concat('&lt;/',name(),'&gt;')"/>
  </xsl:template>

  <xsl:template match="@* | node()">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>

</xsl:stylesheet>

Basically it uses a couple of templates to match the XML elements that need to be converted to text and convert them 'manually'. 基本上，它使用几个模板来匹配需要转换为文本并“手动”转换的XML元素。 The cdata-sections-elements directive does the rest. 其余的操作由cdata-sections-elements指令完成。

When applied to 当应用于 

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<books xmlns:jndi="urn:jboss:jndi-binding-service:1.0">
  <jndi:binding name="books/cat/action/configs">
    <jndi:value type="java.lang.String">
      <urlConfig>
        <defaults catID="1983" subcatID="1987" method="get" onError="keep"/>
        <urlKey name="logo" altURL="def.com">
          <address>abc.com</address>
        </urlKey>
        <urlKey name="logo1" altURL="def.com">
          <address>abc.com</address>
        </urlKey>
      </urlConfig>
    </jndi:value>
  </jndi:binding>
  <jndi:binding name="books/cat/romance/configs">
    <jndi:value type="java.lang.String">
      <urlConfig>
        <defaults catID="1983" subcatID="1987" method="get" onError="keep"/>
        <urlKey name="logo" altURL="def.com">
          <address>abc.com</address>
        </urlKey>
        <urlKey name="logo1" altURL="def.com">
          <address>abc.com</address>
        </urlKey>
      </urlConfig>
    </jndi:value>
  </jndi:binding>
</books>

produces the expected result: 产生预期的结果：
